The Process of applying calcined petroleum coke in Various Industries
Steel Industry Process

The production begins with sourcing high-quality petroleum coke.
It undergoes calcination at temperatures exceeding 1200°C.
Post-calcination, the material is crushed and sized before being used in steel-making processes or sold as anode-grade material.

Refractory Industry Process

Similar initial steps are taken with petroleum coke.
After calcination, additives may be mixed with the product to enhance specific properties required for refractory applications.
The final mixture is shaped into bricks or castables that can endure extreme heat.

Aluminum Production Process

Petroleum coke is processed through calcination before being formed into anodes.
These anodes are then baked at high temperatures to achieve desired physical characteristics.
Once ready, they are utilized in electrolytic cells during aluminum extraction.

Battery Manufacturing Process

Calcined petroleum coke is integrated into composite materials used in electrodes.
It undergoes further processing involving mixing with other conductive materials and binders before being shaped into battery components.
Testing follows to ensure performance meets industry standards before mass production.
